Midterm Review Part 1

Front

What gases were present in the early Earth's atmosphere?

Back

The early Earth's atmosphere contained carbon dioxide, carbon monoxide, water vapor, but lacked oxygen.

Front

What happened to the water vapor in the early atmosphere?

Back

The water vapor condensed to form the oceans.

Front

What type of plate boundary is most associated with metamorphism?

Back

Convergent plate boundaries are most commonly associated with metamorphism.

Front

What geological structure forms from the collision of two continental plates?

Back

A continental mountain forms as a result of the collision of two continental plates.

Front

Where are mafic minerals most likely found?

Back

Mafic minerals are most likely found in locations B and D.

Front

Define 'mafic minerals'.

Back

Mafic minerals are silicate minerals that are rich in magnesium and iron.

Front

What is the significance of the convergent plate boundary?

Back

Convergent plate boundaries are significant for the formation of mountains, earthquakes, and volcanic activity.

Front

What is the role of water vapor in the early Earth's atmosphere?

Back

Water vapor played a crucial role in the formation of oceans and influenced the climate.

Front

What is a continental volcanic arc?

Back

A continental volcanic arc is a chain of volcanoes formed at a convergent boundary where an oceanic plate subducts beneath a continental plate.

Front

What is the difference between mafic and felsic minerals?

Back

Mafic minerals are rich in magnesium and iron, while felsic minerals are rich in silica and aluminum.
